Hi, I'm new here. Can anyone tell me what sort of fossil I've found? Animal or plant? It is a string of roundish indentations about 1/16" that tapers in size towards the ends. I found this near Bushkill Falls, PA. Thanks!

You couldn't have asked this in a better way, because a crinoid is an animal that looks enough like a plant that it is called a "sea lily". They are related to starfish and sand dollars; true living fossils, they have been around for nearly a half billion years!

That is a very nice crinoid stem you have their. From my expierance the shape of that stem tells me that it is a piece that was close to the head of the animal. Do both ends come out of the rock? Does one end have a bumb in the rock? It is posible that you may have more than what u are seeing their. I dk what your expeirance with fossils is but it might be worht poking around on it to see! BUT BE GENTAL!

For some reason when I look at that, I see what looks like the Girtyocoelia sponge.
I could be way off. Are their small holes in them?

Years ago I had read of rare occurrences of complete crinoids from that area. You may have found the good layer(s) for them. I would return to the location and look for more. And as Crinoid Queen mentioned look out for specimens that are still slightly buried under the matrix. But FYI, watch where you are hunting as the national park folks don't take kindly to collecting.

Also, the state(PA) geological survey has good maps and other publications for that area.
